Recently, some scientists have tried to prove that is not, income itself, but inequality in income, that causes negative effects on health. This, kind of approach is named relative income hypothesis, in contrast to the absolute, income hypothesis. Another approach, held mostly by academic economists, denies, the existence of a causal link between income and health, and supports the opposite, causality relationship, which considers the initial stock of health as the determining, factor of individual income and wealth. The first part of the paper provides an, overview of the existing literature on the connection between socio-economic variables, and health in industrialized countries.
